Do not install a PeerMaster adapter in slot 4 of a Model 85
or 95 server. Pressure resulting from contact with foam mounted to
the side panel might result in damage to the adapter or computer.
Ed. So if you REALLY
want to run two Peermasters in a 85 or 95, then you must pull some of the
foam off the side wall cover. You can only use Slot 2, 3, and 4 for form
factor 5 cards (eg. RS6K cards). AND
you cannot put two RS6K form factor cards next to each other (cooling).
So you are limited to Slot 2 and Slot 4.

82503 Dual Serial Transceiver (DST) 29042104.pdf The 82503 includes on-chip AUI and TPE drivers and receivers
82593, and 82596). This component incorporates six LED drivers to dis-
play transmit data, receive data, collision, link integrity, polarity
faults and port selections, allowing for complete network monitoring by
the user. The transmit, receive and collision LEDs indicate the rate of
activity by the frequency of flashing.

82C54 CHMOS Programmable Interval Timer23124406.pdf Three independent 16-bit counters, each capable of handling
clock
inputs up to 10 MHz. All modes are software programmable. The 82C54
is pin compatible with the HMOS 8254, and is a superset of the 8253. Six
programmable timer modes allow the 82C54 to be used as an event counter,
elapsed time indicator, programmable one-shot, and in many other applications.

ADVANCED ADAPTER TECHNOLOGY PeerMaster adapters employ a "deep" design (each adapter
has its own processor), enabling the adapters to off-load selected LAN
functions from the server processor. The PeerMaster attaches to the
MC bus with the "Miami" module, which supports 80MB/sec data-streaming
mode and peer-to-peer data transfers across the MC. The advanced
channel interface enables 64-bit wide data transfers direct from adapter
to adapter, with a performance improvement up to four times that of currently
available Ethernet adapter alternatives.

What is the card edge connector for?

From Peter
>Will this adapter work with Windows 95?
No. All 4 adapters share 1 interrupt.

>And will this device take the place of an external hub?
No. It is a "4 single adapters on one card" ... not a hub.

The Quad-BT or -B2 PeerMaster provides the ability to
connect your server to four separate 10Mbps Ethernet LAN segments.

These adapters support:
40MB/sec data transfers between host PC and adapter
64-bit wide data transfers among ports on an adapter
80MB/sec data transfers among ports across multiple adapters
with no host processor intervention
High performance means to forward cross-segment traffic without
impacting server performance
64-bit data transfers across the Micro Channel at burst
rates of 640Mbps, which equals the total bandwidth of 64 Ethernet ports
(Only IF you have a 500 class system
with six Peermasters!)

Interrupt Level The prioritized interrupt request line on which the adapter
interrupts the system. The interrupt level may be shared with another adapter.
The highest to lowest interrupt priorities are:
<Level 3>, 4, 5

Streaming Data Enables or disables the Streaming Data feature of the
adapter as both a bus master and a slave. Disable causes the adapter to
use the basic data transfer procedures. Streaming data procedure is supported
when enabled.
<Disabled>, Enabled

Selected Feedback Return Checks for and reports loss of selected feedback return
by the bus master of the adapter.
<Disabled>, Enabled

Address and Data Parity Enables or disables the address and data parity checking
and generation by the adapter.
<Disabled>, Enabled

First Shared Storage Window Location There are two independent windows into the random access
memory (RAM) on the adapter. This is the first window that is located in
the read-only memory (ROM) or RAM area. This window is either 8KB
or 16KB

Note: The second window is
used for peer data transfers. The setup program automatically selects this
window above the 1MB boundary in Micro Channel address space. For Model
85 setup instructions, see “Special Instructions for Model 85” below

Special Instructions for Model 85 To provide for peer data transfers, Quad PeerMaster adapters
support a system bus window into their local memory. The location of this
window is normally selected, verified, and reserved by the automatic configuration
program during the adapter installation process. Due to limitations of
the setup program provided on some IBM Model 85 servers, however, this
window is not reserved by the automatic configuration program. Instead,
the device driver provides a default window location for each installed
Quad PeerMaster adapter. The default window location of each installed
adapter is based upon the expansion slot of the adapter in the following
manner:
Conflicts cannot be detected and resolved by the device
driver. Use the setup program on your system to manually verify that conflicts
do not exist with the default window locations. You may override the default
window locations to resolve possible conflicts. The MEMORY keyword allows
you to override the default values. This keyword specifies a system bus
address for the adapter window base, as follows:
